Compact Reconfigurable UWB Slot Antenna for Cognitive ... Abstract: A very compact reconfigurable ultrawideband (UWB) stepped-slot antenna for cognitive radio (CR) applications is presented in this letter. The proposed antenna operates in two modes: UWB mode for sensing application and communicating mode for different narrow/wideband communication applications.

Abstract. In this paper, a survey on ultrawide band and reconfigurable antennas for cognitive radio application is presented. Cognitive radio is an intelligent wireless communication system that is aware of its surrounding environment (i.e., outside world), and uses the methodology of understanding-by-building to learn from the environment and adapt its internal states to statistical ...
